Okay. i'm going to go through how i make units, so it may not help you much if you don't have the same programs.
1) Choose the unit you are going to edit.
2) Open the flic you are going to edit in FLICster
3) Go to "export", change the file name if you want, and choose where you want the files to be exported to. Lets call it File 1.
Note: when you export something, it asks if you want to open the FXM. click "yes" to open this file. this is the animation that all of your changes will show up on.
4) Open Paint Shop Pro 5.
5) Open the .pcx file in File 1.
6) Start making changes to the individual frames.
Note: it is a good idea to check back in FLICster every now and again to make sure that the editing is smooth. if you are pasting something (like a new helmet) over the old, check back to FLICster every three frames of so in case you have misplaced one of the helmets by a pixel or two. 1 pixel can make all the difference. also, if you are using PSP5, ctrl-e is paste. ctrl-v is paste as new image.
7) when you have made all the changes you want, and it looks good in FLICster, go to the "export" tab of the FXM file.
8) change the file name and where you want it to be saved if you want.
9) click export.
10) if you now go to the file menu in FLICster, in the "last four things that were opened" part, you should see "InsertUnitNameHere""whatever animation you were animating".flc (for example, RatOgreAttack.flc)
11) open this to see your newly created flic.
hope this helps
and good luck.
you can also edit pallettes and stuff, but i would leave that until you've got the hang of basic C'n'Ping. have fun!
